Be it known'that we', FREDERICK MAN and `JaMEs1 M 1in IsoN"TEaM ER, both citiaensofthe Unitedl States, and residents of Evansville, in the county ofVanderburg;v and lState fri-Indiana, have 'in -vented anew and-Improved4 Shearsfoi which the Aiol.

O ur invention'relates -to scissors orsh e'ars`. 'v Scissors and'shearsas heretofore Aconstructed have been `seriously defective at' the pivotscrew'inasmuchl as this screw has'to'be quite tightiithe blades are' to.

cu-'t closely-which :increases the'labor of using the .seissors orshears'while, oni the other hand, if the screw is 'loosened to rendertheuse ,ofthey shears o r sc 'issorsless laboriou's, the blades wabble'andout. unsatisfaetorilyg' another defect is the liability of rust'gatherngaround :the screwii it remains-loose.' VTo overcome the foregoingdefects, `We\,provide .the

inner. facesof the vblades of scissors or shears withrei cessed or eut'away portions at'their pivotal-`parts and position-the -pivot screw Icentrallyl .of said recessed vpartsf This results in' a thinfiingjsf theblades' and' relievesthem ofl great stiffness atjtheirpivotal parts andenables the screw to be tightened Without causing great, friction atthel pivot and yet, 4on.account-oi the -deereased thiekne'ss'of theblades around the pivot, they-yield to the tightening of the'p'ivotscrew;and-fa-` tensioning yefiec't isproduced thereat which causes theblades to. shear' 'or cut close to each other, enabling elean' cuttingeffects to be had Iwithout' increase of `Alabor' in using theshea'rs orscissors andIobviating'v Wabbling' blades, the accumulation of rust andether 'disadvantages AWe also` provide a novel construction at the'tipsof' the blades in the' form 4oiprojections Whichhave Hat inner facesthat are adapted'tome'et v.beyond the termination of the 'cutting 'edges'of the blades in the line of sucl1' cutting edgesand therebyobtain'means for engaging-and supporting ',the mater rial Ito be cut directlyin line with -the cutting-edges, 40

facilitating the operation of cutting,. preventing vin- 'jury to thematerial, and also preventingtle tips-of i the blades rorn passing 'outof the cuti IIL the present invention meansa'r'e alsoprovidedl forkeepingthe material being eut fromA enteringgor' catching the pivotalparts ofthe shears or scissors.

Referring to the first threefig'uress we have shown two shear'imenihersa and a/. Each of these vmembers is provided with a recess oroffsetblcentrally located with respect toa pivot'screw c ofthe shears,andl adaptf Letters Patent. "ipp1imi0n-siedlh1y 21, 190e sentirlo.270,670'.

First,v itallows a 'iull closwithoutdsengaging the latter' from V Jthel inaterialjfupon whichtheyfare'oper'ating. Whenflongrapid cutting is required, on lmaterialthat will 'not rip or paper, and on curved, iiregula1 eutting, this is-very useful, One -dific-ultyn these forms of'cuttinglias-always beenthat when 'the shears cut. to their points, one point 'or Aentf-and:itis necessary' th'en`to' guide the shears back to' the-'cut inthematerial,` which-results-in a lbssjoi;A

time, and also may result iii-'starting-thenew eut at aslight-angleto'the old. vIn addition to this,V theen- --largement 'hofthe lower blade-is always yin advance up the materiaiso thevshears canbe pushed forward, using the full sweep of' th'e'b'lades without makingThe recessed part "bof the-members 'of the sheas'act as a' tension, asit is' bow-shaped, and 'when' the-parts -are drawn together .by the'screw c has a'tendency to bring and hold the cuttiiigferlg'es oftheblad-estogether,l especially at the points. The recesses b thin theAniaterial aroundth'e pivot screw andrender it sprihgyor edges,:'lhivsformation oftheends of the blades ae' ofthe eutting'edge whenclosed and it'thereiore holds 'fthe other passes to the wrongside; ofthe material being 4 any effort 'to guide thegsliears inavertieal'direction or to keep them'in :engagement with the material.. f

.This prevents the shears from injuring-'the material,`

.getting'out oi'line, and-from slipping 'outof the cut'. A n' additionaladvantage of these enlargements will also beobserved; Shears arefrequentlyused indeceand other places, and the abutting Hat surfaces oithese enlargements canfbe employed for grippingpins and pulling them outof their places.' ',The form of shears shownin the rst`tl'1ree figuresis especially-adaptlxl Y forthe use of dry-goods clerks, although it isalso capable'of general use, and its'utility will not be z nater'inlly'lessened in anyl of thepurposes for ,which shears are Vordinarilyemployed.

The; Wa,yinrwl1 ich this, extension Works Wlll be obvious When-it is understoodthat upon the -opening of the 4shers to their extreme limit thisextension will notpass beyond the-edge oi the other-y blade,thus-keeping the 'cloth well within the space between the blades.yAnother extensionv n isnlso shown oil-one of the Vhandlesotheb1ades,.to act as a. bearingyhen the shears 'are openedto their'full eictent. `1
